Post all your Arduino, ESP16, ESP32, ESP8266 etc projects here. This thread is for inventers, programmers, hackers, engineers. Let us get creative.
 
It seems like the ESP32 wifi soil sensor can be repurposed as a rain gauge. Preliminary tests shows that it may be accurate on 0.1 mm. Now I need to see if temperature will effect the capacitive sensor. The gauge will be emptied with a siphon.702089

This look like a great Arduino / ESP32 / ESP8266 course.

Question, i want to try out some arduino things, however i see some acronyms i don't understand, i'll be buying a Arduino pro mini 16mhz, though on sites like communica i see acm and bsk versions, can somebody tell me what that means? i see various other items that also have the same acronym.

ACM/BSK is just the supplier name (I think). Just remember that the Pro Mini must be programmed with a FTDI serial chip or similar. I would go for the Pro Micro, which is faster, same form factor-ish, and has a USB port to connect to your computer. The Pro micro is more expensive, but have much more features (USB HID, USB Serial). Just go with the 5V one.
 
score? :P I have not checked the score. It plays the game for a couple of minutes until the first "bird" appears.

The bird flies higher than the sensor ... You could add a second LDR to fix that issue but then when the game starts speeding up the timing will start to fail and the dino will start hitting stuff.

I'm sure there are ways to fix it but I will leave it as is for now. :)
 
I have done a ton of projects using them, my garage and front gate are automated into Home Assistant using an ESP32 with 2 relays and a hall effect sensor.
The relay has wires soldered into an old remote and just does dry contact push actions.
The hall sensor reads a magnet on the garage door to tell Home Assistant if its open or closed, if the door is left open then an automation sends my phone a push with an option to close it and Alexa says "You left the garage door open again dumbass"
 
Similar to @Rocket-Boy Also have a ton of ESP32's (Wemos D1 minis which are dirt cheap) around the house, garage, greenhouse with DS18B20 temp sensors, all sending data to OpenHab.
On the doors using magnet sensors also reporting to OpenHab. When the sensors trigger it sents a call to ZoneMinder to start recording on a the cameras.
